An exemplary integration into an active kitchen, designed for comfort 12 months a year
At AirGreen , we prioritize discreet, efficient, and sustainable HVAC installations . This project in a home in Rosemont–La Petite-Patrie (Montreal) illustrates our approach: a Gree wall-mounted heat pump installed above the kitchen cabinets, perfectly integrated into the aesthetics of the space and sized to provide stable comfort for both heating and cooling.
Client context and objectives
The owner wanted to air condition the most heavily used area of the house—the kitchen and adjoining dining area—while also increasing the heating backup during the off-season and winter. His priorities:
-
maintain a uniform temperature despite the heat input from cooking and sunlight;
-
reduce energy consumption;
-
avoid any loss of space or visual disruption in the room.
We recommended a Gree residential wall-mounted heat pump , known for its reliability, its inverter compressor and its very low noise level.
What we have achieved, step by step
Choosing the interior location
The indoor unit was positioned at the top of the wall, above the kitchen cabinets , under a ceiling with recessed spotlights. This location has three advantages:
-
Controlled stratification : the treated air is blown at the right height to evenly mix the rising heat from the kitchen.
-
Optimized horizontal diffusion : the air outlet directs the air along the ceiling towards the dining room, without creating a draft on the work surface.
-
Aesthetics : The Gree's gray glass housing blends naturally with the wood finishes and blue ceramic.
Drilling and routing of connections
-
Discreet rear outlet with Ø65 mm drilling behind the bottom of the unit.
-
Useful refrigeration length : ~3.5 m up to the side facade overlooking the aisle, limiting pressure losses.
-
External routing under matching capping , with curvature radii respected to preserve the integrity of the insulated copper tubes.
Condensate management
The configuration allows for gravity discharge (slope ≥ 2%), avoiding the use of a pump and therefore any additional noise in the kitchen. The discharge is protected against frost and splashes, with a non-return nozzle.
Electrical connection and protections
-
Dedicated 240V circuit with circuit breaker calibrated according to the appliance plate.
-
Waterproof disconnect box near the outdoor unit, in accordance with the Quebec Electrical Code.
-
Certified conductors and grounding; conduits mechanically secured to resist vibration.
Rigorous commissioning
-
Nitrogen test at 350 psi and leak test (soap + zero pressure drop).
-
Vacuum draw to ≤ 500 microns, stabilized.
-
Torque tightening of flared fittings (compliance with Gree specifications).
-
Calibration of shutters, automatic ventilation settings and testing of heating , cooling and dehumidification modes.
Why a Gree wall-mounted heat pump for a kitchen?
-
Fine modulation : the inverter compressor continuously adapts the power, which maintains the setpoint even during a cooking session.
-
Quiet operation : ideal for living rooms where people talk and cook.
-
Filtration : improves air quality by capturing fine particles transported by natural convection in the room.
-
Seasonal efficiency : high COP in heating and efficient air conditioning from the first warm days.
-
Simplified maintenance : direct access to filters; quick cleaning, without dismantling the woodwork.
Salient installation details to remember
-
High installation above the cupboards, without encroaching on the ergonomics of the work surface.
-
Gravity drain (reliable and silent) to the outside.
-
Short connection limiting losses and optimizing efficiency.
-
Aesthetics : no visible sheathing inside; discreet exterior capping .
-
Comfort : diffusion along the ceiling, avoiding direct airflow onto the occupants.
Measurable results for the client
-
Immediate comfort : rapid drop in temperature in summer and elimination of cold areas near the garden entrance.
-
Thermal stability during cooking: the machine compensates for heat peaks without overconsumption.
-
Reduced bills : in mid-season, the heat pump advantageously replaces electric heaters.
-
Almost imperceptible noise level at low speed, perfect for meals.
HVAC maintenance: our advice for this configuration
-
Filters : Gentle vacuuming every 4 to 6 weeks, washing in warm water as needed.
-
Exchanger : annual professional dusting to preserve heat exchange.
-
Drain : check the slope and exterior clearance before summer.
-
Outdoor unit : maintain free clearance (snow, leaves), defrost the base in winter if there is accumulation.
-
Annual AirGreen visit : checking pressures, tightening, probes and updating parameters.
Grants and Eligibility
High-performance, certified wall-mounted heat pumps may be eligible for current programs (e.g., LogisVert, Hydro-Québec , municipal initiatives). We assist our clients in Montreal, Laval , Longueuil , the North Shore and the South Shore in preparing their files (choice of eligible models, proof of installation, forms).
What sets AirGreen apart in Greater Montreal
-
Precise sizing : selection of BTU capacity based on the internal loads of a kitchen (appliances, orientation, ventilation).
-
Finish : short lines, clean drilling, waterproof sealing and HVAC installation that respects the architecture.
-
Controlled deadlines : measurement, approval, installation and commissioning planned to minimize disruption to life at home.
-
After-sales service : technical assistance and HVAC maintenance reminders to ensure equipment longevity.
Good practices and pitfalls to avoid in the kitchen
-
Avoid blowing directly onto the hood or creating turbulent recirculation: the unit has been positioned to bypass this area.
-
Provide a free air intake for the hood (if external exhaust) so as not to destabilize the pressure in the room.
-
Do not obstruct the front of the indoor unit with decorative objects or baskets above the cabinets.
-
Monitor humidity in cooking mode: use dry mode occasionally when steam is high.
Balance sheet
This Gree wall-mounted heat pump installation in Rosemont–La Petite-Patrie fulfills the objective: precise comfort in a busy kitchen, controlled energy consumption, and clean integration. The client now benefits from a more pleasant space for cooking and entertaining, summer and winter, with a discreet and efficient solution.
